Two-raar HINGE.

Specification of Letters Patent.

Patented Nov. 30, 1915.

Application led July 2l, 1914. Serial No. 852,309.

hinge together with certain improvements thereof.

Objects of this invention are to provide a hinge of only two .parts which .may be applied to hang a screen or thelike at any part of an under side or surface so that the screen may be hung to thetop o-f a window casing either at the margin of the window frame or inwardly fromsuch margin in order that the screen framemay be so located as to be free from interference of stops or molding;- and to provide a hinge of this character which is readily separable so that the screen or window may be easily hung in deeply recessed casings and easily removed therefrom; said hinge being adapted for smooth and even hinge movement in the manner of an ordinary butt hinge.

Another object is the provision of a device of this character, the two parts of which will continue in engagement with one another until after the screen or window, to which it is applied is swung outward at a comparatively great angle from the vertical so as to increase and insure security against accidental disengagementl of the hinge parts when the screen or window is swung outward to open.

Otherl objects and advantages may appear as the invention is unfolded more specifically in the subjoined detailed description.

The accompanying drawings illustrate the invention.

Figure 1 is a fragmentary perspective view embodying the invention. Fig. 2 is a perspective view of two parts of the hinge shown in Fig. 1, detached and disengaged from one another. Fig. 8 is a vertical section of some of the parts shown in Fig. 1, the lower portion of the window frame and swinging member also being shown. Fig. 4: is a view of two stamped hinge blanks from which the hinge members in the preceding views are produced by bending.

A stationary member 1 which` may be a window casing or the like is provided on itsl window aperture marginal face 2 with a stationary hinge leaf or strap 3 that eX- tends outward beyond said marginal face and is bent to form a knuckle 4t. rThe knuckle 4 practically forms complete circles at the end portions and is slotted intermediate said end portions at the back at and is provided intermediate said lend portions in front with an orifice'6, the material between said slot and orifice forming a pintle-bar 7. A swinging member 8 which may bea screen, window frame or the like is provided with a swinging hinge leaf or strap 9 that is bent loutward below the margin of kle 10 of somewhat less width than the slot 5 and orifice 6 and adapted to hook over the pintle-bar 7 and .provided with an eXtension or re-curved tongue 11, the outer end of which is accommodated in the 'orifice 6, said orifice being of suflicient extent to accommodate the tongue in any position incident to it during the operation of the screen from the closed position in solid lines in Fig. 8 to the open position indicated in broken lines, in which open position the outer end of the tongue forms a limiting stop seating against the opposing stop-forming upper edge 12 of the oriiice 6, thus to prevent accidental disengagement of the hinge straps and consequent displacement of the screen.

It will be seen by reference to Figs. 1, 2 and 3 that the edgey of the knuckle t constituted by the pintle 7 is inclosed within the knuckle 10 which is formed as an open hook for engagement with and detachment from the knuckle edge or pintle bar 7 when the leaf 9 is swung away over leaf 3 into a plane approximating parallelism with the plane of said leaf 3 as shown in Fig. 3.

In practical use as clearly shown in Fig. 3, the frame 8 may be swung from the closed position shown in solid lines to the open position in broken lines with the lower end of the frame raised to its maximum height, during which movement the knuckle 10 will be retainedby the pintle-bar 7, thus preventing accidental disengagement of the frame and window casing 1.

To detach the frame' from the window casing it will first be necessary to swing the lower end of the frameupward sufficiently the screen frame in the same direction as i the knuckle 4 to form a semicircular knucto aline the tongue 11 with the slot 5, and then to move the frame bodily inward to withdraw'the tongue from the Slot.

I claim:

l. A two-part hinge comprising leaves bent to form knuckles, said knuckles being interlocked so that the edge of one knuckle is inclosed within the other knuckle, the

.knuckle of one of said leaves being cut away to form a slot and orifice and the other having an extension in the form of an open hook projecting through said orifice; so as to allow the leaves to be connected and separated when the leaves are swung apart into planes that are approximately parallel with each other.

2. A hinge comprising a leaf provided with a knuckle forming substantially complete circles at the end portions. and provided at the back intermediate said end portions with a slot and provided in front intermediate said end portions with an orifice, the material between said slot and orifice forming a pintle-bar; and a second leaf bent outward in the same direction as said knuckle to form a substantially semi-circular knuckle adapted to hook over the pintle-bar.

3. A hinge comprising a leaf provided with a knuckle forming substantially complete circles at the end portions and provided at the back intermediate said end portions with a slot and provided in front intermediate said end portions with an orifice, the material between said slot and orifice forming a pintle-bar; and a second leaf bent outward in the same direction as said knuckle to form a substantially semi-circular knuckle, adapted to hook over the pintlebar, and provided with a tongue having its outer end accommodated in said orifice.

A hinge comprising a leaf provided with a knuckle forming substantially complete circles at the end portions and provided at the back intermediate said end portions with a slot and provided in front intermediate said end portions with an orifice, the material between said slot and orifice forming a pintle-bar; and a second leaf bent outward in the same direction as said knuckle to form a substantially semi-circular knuckle adapted to hook over the pintle bar and provided with a re-curved tongue designed to seat against the upper edge of said orifice when the leaves are relatively swung.

In testimony whereof, I have hereunto set my hand at Los Angeles, California this 15th day of July, 1914.
